Abstract: PROBLEM TO BE SOLVED: To obtain the electronic musical instrument having many kinds of variation curve of parameter values that a user can select to taste while suppressing a rise in the cost by supplying parameter values to a sound source means which generates a musical sound to reflect the acquired parameter values on the musical sound. SOLUTION: In an event process, an MPU 11 reads in a counter value C, a key number K as the number of a key which is pressed or released, and a status S (depression = 1, release = 0) showing whether the key having the key number K is pressed or released this time from a key scan chip 18. Then the MPU 11 decides the key depression (1) or key release (0) according to the status S and when the key is pressed (S=0), a velocity value V is set to 0, thereby performing a note-assigning process. In this process, the key number K and velocity V are sent from the MPU 11 to the sound source 16. The sound source 16 generates a musical sound having the pitch corresponding to the key number K and sound volume corresponding to the velocity V.

Title: Air conditioner inlaid in ceiling
Inventor: YAMAKI HISAMITSU
IPC: F24F1/00
Filed: 1984-01-31
Abstract: PURPOSE:To improve the temperature distrubution when heating by providing a damper that opens and closes an air blowing chamber communicated with one of air outlets. CONSTITUTION:An arrangement, for instance, is made in such a manner that when cooling, a damper 19 is located in a position shown by solid lines to communicate an air blowing chamber 15b with an air outlet 18 on the set plate side 12 so that air may be blown out of outlets 17, 18. That is, the air flowing in from an air intake 16 passes an intake chamber 15a, and turns into the cool air as it passes from a fan 13 through a heat exchanger 14, and ultimately passes through the chamber 15b to be blown out of both the outlets 17, 18. When heating, the damper 19 is switched to a position shown by dotted lines to interrupt the air passage. That is, the air flowing in from the intake 16 passes through the chamber 15a, and turns in the hot air by the heat exhchanger 14 to be blown only out of the outlet 17. In this manner, the air is blown only out of one side when heating, and so, the air can reach the floor at a longer distance, the temperature distribution is improved to reduce the differential temperature between the ceiling and floor areas.

Title: Magneto-optical disk
Inventor: NAKADE TATSUO
IPC: G11B11/105
Filed: 1987-01-27
Abstract: PURPOSE:To obtain a magneto-optical disk having high magneto-optical recording and reproducing characteristics and excellent long-term durability by using metal oxide having a specific compsn. for a dielectric film as an interference film. CONSTITUTION:The metal oxide having the compsn. which is any among AOa, DOa or AxD1-xOa (where A is Zr or Cr, D is Hf or Zn, a>=0.5, 0<x<1) is used for the dielectric film as the interference film. In this component, (a) is stable in a wide range and, therefore, said component absorbs oxygen even if the oxygen is intruded into the film from the outside. The high effect as a protective film to prevent the oxidation of a magneto-optical recording medium layer is thus obtd. The metal is formed in the dielectric film and the transparent film having uniform quality is not formed if (a) is below the lower limit. On the other hand, the oxygen or nitrogen is excessive and this excess oxygen or nitrogen intrudes into the magneto-optical recording medium layer to deteriorate the characteristics thereof if (a) exceeds the upper limit.

Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of accessibility from a host device at the time of a fault of an HDD part and also to shorten a recovery time of the faulty HDD part to quickly secure its redundancy. SOLUTION: If a fault of an HDD part is detected by an HDD fault state detection means 24 when a command is taken out of a command queue 28, a command processing means 29 checks whether the internal hardware load of its own device adapter is higher than a prescribed level via its internal HW load measurement device 25. If the above hardware load is heavier than the prescribed level, the command is transfered to another device adapter to ask this adapter to execute the command when a standby redundant state detection means 26 detects that its own disk adapter is working, and that another device adapter is set in a redundant state. Thus, the command is transferred to another device adapter by a command transfer means 27.
